Seven forced to apologise after MKR gaffe

Channel Seven has been forced to apologise after it gave away the outcome of last night's My Kitchen Rules episode in an ad break during the show.

Viewers of the hit reality program in Adelaide took to social media to blast the network when a promotional ad showed father and son pair Mick and Matt still in the show.

The Comeback Kitchen episode gives eliminated couples the chance to re-enter the main competition, but 40 minutes into the show, Seven showed a preview of this week's show which included Mick and Matt.

Seven admitted the mistake and issued an apology, blaming the gaffe on a programming error.
